TH READ- DOUBLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 423,847, dated March 18, 1890.

' Application filed February 2, 1889. Serial No. 298,464. (No model.)

To all whom it may concern:

Be it known that I, ALBERT M. \VHITE, a

citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Thread- Doubling Machines, of which the following is a specification.

My invention relates to improvements in thread-doubling machines; an d the Objects of my invention are to improve the efficiency of the machine, to produce a machine specially 7 adapted for uniting three strands, and to combine with the movable guide a stop-motion.

In the accompanying drawings, Figure 1 is a front elevation of so much of a thread doubling and winding device as is necessary to show my improvement. Fig. 2 is a side elevation thereof, with some of the parts in verand Fig. 7 is a detached View showinga modification.

A designates a driving-shaft bearing friction-driving pulleys B B, upon which the heads of the spool C rest and by which they are driven, and D designates the guiding-bar, over which the united strands are guided when being wound upon the receiving-spool C, all as in ordinary thread-winding machines and for which any known'driving mechanism and receiving-spools may be substituted.

I consider it unnecessary to show the entire frame of the machine, as any frame which will support the parts in the respective positions shown will answer all the requirements of my invention.

7, 8, and 9 designate longitudinal bars of the frame, upon the lower one of which the several delivery spools or bobbins 10, containing the threads to be united, are arranged for unwinding in any ordinary manner.

Upon the bar 8 of the frame I secure the tension-regulating devices of my winder.

11 designates a bracket hearing at its upper and lower ends the plates 12 and 13, having notches 14 formed in their edges, which notches serve as upper and lower fixed guides for the several strands to be united.

Upon the lower plate 13, I arrange a rod 15, which is connected to said lower plate 13 by a ball-and-socket joint 16, whereby said rod can move as on a universal joint. The upper end of this rod 15 bears the movable threadguides 17, which should be arranged about midway between the upper and lower fixed thread-guides, as shown. I have illustrated three of these movable guides and three strands of thread 18 as being united. These strands run from the delivery bobbins or spools 10, through the lower fixed guides 14, then inwardly and upwardly to and through the movable guides 17, then outwardly and upwardly to and through the upper fixed guides in the plate 12, and then upwardly to the uniting-point on the guide-bar D in front of the receiving-spool C. hen thus being united, if one of the strands is strained more or less than the others, the movable guide immediately moves by reason of its universal joint into a position to equalize the varying tension of the strands, all substantially in the manner shown and described in reissued Letters Patent N 0. 10,364, to Albert L. VVash- 30 burn, dated August 7, 1883, but differing therefrom in the arrangement of the movable guide upon a rod having a universal joint.

While I have shown this doubler as uniting three strands, it may be used for uniting two 5 strands by merely dropping one of the strands or by dropping one of the strands and placing the remaining two in the notches 19 of the upper and lower fiXed guides, and in like manner any desired number of strands may 9 be united by providing a suitable number of notches for the upper and lower fixed guides and a corresponding number and position of the movable guides at the upper end of the rod 15. Thus if the machine is constructed specially for uniting only two strands, then there need be only two notches in the upper and lower fixed guides and only two movable guides on the upper end of the rod.

IVhile greater usefulness is attained when my machine is used for uniting three strands than when only two are united, it is of an apparent advantage to have a machine that may readily be changed for use in uniting two or three or other number of strands when 7 desired, and so far as I know no such machine has ever before been produced or patented or described in any printed publication. In order to accomplish the best results, the moving thread-guides should have the greatest possible freedom of movement, and this they have at all times in my machine whether two or more strands are being united. I also extend the rod 15 some distance below the universal joint 16 and immediately underneath it I arrange a circular step 20 upon the upper side and outer end of the stop-actuating lever 21, said step being centrally located with reference to the axis of the rod 15 when said rod is in vertical position. This lever 21 is weighted, as at 25, and provided with an upwardly-projecting arm 22, which bears upon the lower end or arm of the stop-lever 23, as shown in Fig. 2. The contacting ends of the arm 22 and lever 23 are also illustrated by broken lines in Fig. 1. The upper end of the stop-lever 23 carries a swinging arm 24, that rests upon the periphery of one of the driving-wheels B, immediately under one of the heads of the spool C, as shown in Fig. 2.

In the ordinary operation of the machine the wtrying tensions of the several strands will not move the rod 15 sufficiently out of an upright position to throw its lower end off the face of the circular step 20, but in case any of the strands should break the remaining strands will pull the movable threadguides so far to one side that the lower end of the rod 15 will slip off the circular step 20, and thereby leave the stopaetuating lever 21 free to be acted upon by its weight 25, and through the arm and lever 23 to operate the stop mechanism by pushing the swinging arm, 24 under one of the heads of the spool C, as indicated by broken lines in Fig. 2, and thereby lift one end of the spool into the position shown in Fig. 5. In this position there will not be friction enoughupon the other head of the spool to drive it, and consequently it is immediately stopped by the stop mechanism so soon as one of the strands is broken.

IVhile I have illustrated a particular kind of stop mechanism, it is one that is well known, and other stop mechanisms may be substituted therefor, the essential feature of my combination consisting of the lower end of the rod that supports the movable threadguides, the circular step, and the stop-actuating lever 21, whereby the lower end of said rod upon the breaking of a thread immediately moves to one side and permits the stop mechanism to act.

In Fig. 7 I have shown a slight modiiica tion of the circular step 20 at the lower end of the rod 15, consisting of securing said step to the lower end of said rod, and providing an upward projection 26 on the top of the stop-actuating lever 21; but the operation is the same as that already described, only the step slips off the projecting end 26 instead of having the projecting end of the rod slip olf the step, the result being the same in both cases.

My invention resides chiefly in mounting the movable thread-guides on the rod which vibrates upon a joint, and in combining therewith the stop-aetuating lever, and therefore the other parts are shown and described for the purpose of showing the connection of my invention therewith, and they may be changed, as desired, so long as these essential parts of my invention are retained.

I claim as my invention- 1. In a machine for uniting threads, the combination of the upper and lower threadguides and intermediate movable guides supported on a rod having a universal joint, and adapted for operating upon two or more threads, substantially as described,and for the purpose specified.

2. The combination of the upper and lower thread guides, the rod 15, vibrating on a universal joint, and provided with movable thread-guides at one end, while its opposite end projects beyond the joint, the circular step, and the stop'aetuating lever, substantially as described, and for the purpose specified.

3. The combination of the upper and lower thread-guides, a rod vibrating on a joint and having movable thread-guides at one end and a projecting end at the opposite side of said joint, the step, and the stop-actuatinglever, substantially as described, and for the purpose specified.

4. In a machine for uniting threads, the combination of upper and lower threadguides, a support for movable thread-guides intermediate between said upper and lower guides, a vertical rod having in connection with said support a universal joint by which it is mounted, and movable thread-guides mounted on said rod at a plane above said joint, substantially as described, and for the purpose specified.
